F13LD — Fully Implicit Engine for Lattice Design

Browser-Native · WebGL · No STL Intermediates

f13ld.app ↗

The open-source tool suite I build under Not a Robot Engineering. Nine single-file HTML tools, fully implicit from field math to watertight 3MF export. No proprietary lock-in. No mesh intermediates.

TPMS
Surface Design

Implicit TPMS and PI-TPMS surfaces with real-time WebGL preview and FFT-CG mechanical homogenization.

Sweep
Parameter Space

Multi-dimensional parameter space exploration with curated material databases and pore architecture metrics.

Grain
Stochastic Fields

Directionally biased microstructures — spinodoids, Gaussian random fields, and hyperuniform kernel fields.

Noise
Stochastic Fields

3D stochastic scalar fields as isosurface lattices — a non-periodic alternative to crystallographic TPMS.

Bundle
Fiber Structures

Helicoidal fiber architectures — Bundle, Helicoid, Braid, and Plain Weave lattice topologies.

Beam
Beam Lattices

Parametric strut-and-node truss lattices, thickened implicitly into watertight scaffolds for additive manufacturing.

Ingest
Data Pipeline

Validate and ingest structure data from TPMS and Sweep into the Vault database with automated quality checks.

Vault
Structure Library

Curated library of validated implicit lattice structures, searchable by application domain and performance target.

Mesh
Geometry Export

Composite SDF meshing and watertight 3MF export — the output stage for all F13LD designs.

Specialties

Where standard CAD
stops, this begins.

Independent computational design consultancy focused on orthopedic implants, metamaterials, and bioinspired structure — from concept geometry to validated, print-ready deliverables.
